Support structure for drum

ABSTRACT

A support structure for a drum includes a fixing seat, a combination seat, two displacement seats, two connecting tubes, two links, two universal connectors, two connecting seats, and two foot pads. Each of the two links and the respective connecting tube form the foot post of the support structure. Thus, the inclined angle of each of the two foot posts relative to the combination seat is arbitrarily adjusted rapidly, easily and conveniently, thereby facilitating the user using the support structure.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a support structure for a drum, and more particularly to a support structure for a drum, wherein the inclined angle of each of the two foot posts relative to the combination seat is arbitrarily adjusted rapidly, easily and conveniently, thereby facilitating the user using the support structure.

[0003] 2. Description of the Related Art

[0004] A conventional support structure for a drum in accordance with the prior art shown in FIGS. 1 and 2 is mounted on each of two sides of a drum 90 and comprises a fixing seat 10A, a combination seat 13A, and a foot post 18A. The fixing seat 10A is locked on a frame 92 of the drum 90. The fixing seat 10A is formed with a through hole 11A. The combination seat 13A is secured on the fixing seat 10A. The combination seat 13A has a first side formed with an engaging portion 14A and a through hole 15A. The combination seat 13A has a second side formed with a receiving hole 16A and a connecting hole 17A. A bolt 1A is extended through a washer 2A, the inner side of the frame 92 of the drum 90, the through hole 11A of the fixing seat 10A and the through hole 15A of the combination seat 13A, and is screwed with a wing nut 3A, thereby securing the combination seat 13A on the fixing seat 10A. The foot post 18A has one end received in the receiving hole 16A of the combination seat 13A and formed with a connecting hole 19A. A pin 4A is extended through the connecting hole 17A of the combination seat 13A and is riveted in the connecting hole 19A of the foot post 18A, thereby securing the foot post 18A on the combination seat 13A. When the bolt 1A is unscrewed from the wing nut 3A, the combination seat 13A is pivoted relative to the fixing seat 10A, thereby adjusting the inclined angle of the foot post 18 relative to the fixing seat 10A and the drum 90. However, the inclined angle of the foot post 18 relative to the fixing seat 10A and the drum 90 cannot be adjusted easily and conveniently, thereby causing inconvenience to the user. In addition, the foot post 18 mounted on each of the two sides of the drum 90 cannot support the drum 90 rigidly and stably, thereby affecting operation of the drum 90.

SUMMARY OF THE INVENTION

[0039] Each of the two connecting tubes 35 is secured on a respective one of the two displacement seats 30. Each of the two connecting tubes 35 has a first end received in the receiving hole 32 of the respective displacement seat 30 and formed with a connecting hole 36 aligning with the connecting hole 31 of the respective displacement seat 30. The support structure of the present invention further comprises two insertion pins 4 each extended through the connecting hole 31 of a respective one of the two displacement seats 30 and each secured in the connecting hole 36 of a respective one of the two connecting tubes 35 by riveting, so that each of the two connecting tubes 35 is combined with the respective displacement seat 30 integrally. Each of the two connecting tubes 35 has a second end formed with a threaded locking hole 37.

[0040] Each of the two links 50 is a circular rod and is secured on a respective one of the two connecting tubes 35. Each of the two links 50 has a first end inserted into the second end of the respective connecting tube 35. The support structure of the present invention further comprises two wing-shaped bolts 5 each screwed into the threaded locking hole 37 of a respective one of the two connecting tubes 35 and each urged on the first end of a respective one of the two links 50. Each of the two links 50 has a second end formed with an inner screw bore 51.

[0041] Each of the two links 50 and the respective connecting tube 35 form the foot post 18 of the support structure of the present invention.

[0042] Each of the two universal connectors 52 is mounted on a respective one of the two links 50, and includes, a support seat 53 and a rocking rod 56 rotatably mounted on the support seat 53. The support seat 53 of each of the two universal connectors 52 has a top face formed with a cone-shaped chamber 54 and a bottom face formed with a screw bore 55.
